Spherical shaped BiVO4 photocatalysts were prepared by the solution combustion synthesis method. The as-prepared photocatalysts were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and ultraviolet-visible diffraction reflection spectroscopy (UV-vis). The BiVO4 crystallites showed a monoclinic structure with a spherical shape particle with diameter of about 400-600 nm. Ultraviolet-visible diffusion absorption spectra indicated that the band gap absorption edge of pure BiVO4 was 523 nm, corresponding to a band gap energy of 2.45 eV. It was also found that the photocatalytic activity of degradation of methylene blue improved when the molar ratio of fuels to oxidizer was 5.
